He said Category 1 involved images focused on the subjects’ genitals, which could involve sexual acts. Category 2 involved full or partial nudity but didn’t focus on the privates of the subjects, and Category 3 involved clothed or mostly clothed children posed in provocative manners.

“I found a total of 5,264 images. Of those, 2,257 were unique that I categorized as Category 1,” Haataja told a six-man, six-woman Court of Queen’s Bench jury.

He also found 1,730 images in Category 2 and 1,004 in Category 3.

On the computers and hard drives he examined, Haataja also found movies he considered to be child pornography.
